Sapphire-Derived Fiber (SDF) is an advanced high-performance optical fiber fabricated using the rod-in-tube method with single-crystal sapphire (Al₂O₃) as the core material.
Compared with conventional silica optical fibers, SDF offers exceptional thermal stability, mechanical strength, and resistance to corrosion, radiation, and high-pressure environments. It is specifically engineered for optical sensing and signal transmission in extreme conditions where traditional fibers cannot operate reliably.
With tunable optical parameters and flexible structural design, sapphire-derived fiber is widely applied in high-temperature sensing, infrared transmission, and harsh industrial monitoring systems.
Ultra-High Temperature Resistance
Operates up to ≤1400°C (short-term) and ≤1000°C (long-term), ensuring stable performance in extreme thermal environments.
Outstanding Mechanical Strength
Single-crystal sapphire structure provides superior hardness, wear resistance, and long service life.
Excellent Infrared Transmission Capability
Supports wide wavelength transmission (typically 1300–2000 nm), ideal for infrared sensing and spectroscopy.
Low Transmission Loss
Optimized structure ensures attenuation ≤2 dB/m @1550 nm, enabling efficient signal transmission in harsh environments.
Flexible Transmission Modes
Supports single-mode, few-mode, and multi-mode configurations to meet diverse application requirements.
Customizable Optical Design
Core diameter, cladding size, coating, numerical aperture (NA), and refractive index modulation can be tailored.
